• Quatrefoil - A stylised four-circle design, itself contained within a larger circle, with Gothic origins and often seen as window designs in ecclesiastical architecture. The use of the motif was popular in Gothic Revival furniture of the 19th century.
• Bronze - An alloy of copper and tin, traditionally in the proportions of about 9 parts of copper to 1 part of tin.
  
  The discovery of bronze in Western Asia in the 4th century enabled people to create metal objects which were superior to those previoulsy possible because of its strength and hardness, and it has been used throughout the world for weapons, coins, tools, statuary and other decorative items.
  
  It is very fluid in a molten state, and its hardness, strength when set, and non-corrosive properties makes it most suitable for casting sculpture.
• Song Dynasty - The Song Dynasty was a ruling dynasty in China from 960 to 1279 AD. It was divided into two periods, the Northern Song (960?1127) and the Southern Song (1127?1279). The emperor was the ultimate authority, but he relied on officials who were selected based on their merit and skills rather than their family background or social status. The Song Dynasty was a period of great artistic and cultural achievements, particularly in the areas of poetry, painting, and calligraphy. The Chinese invented the printing press during this period, which revolutionized the spread of knowledge and ideas. During the Song Dynasty, China had a prosperous economy and was a centre of international trade, particularly in luxury goods such as silk, tea, and porcelain. The use of paper money became more widespread during this period, facilitating commerce and trade.
